My daughter Sarah Tetzloff has a 2nd great grandfather August Tetzloff, b. 1852 in Prussia, who came to Milwaukee, prob. in the early 1870s, married and was living in Fond du Lac Co. 1880. The family moved to Floyd Co. Iowa around 1880 where he was naturalized early 1880s. He was said to have come with 4 or 5 brothers. We are trying to find out who the brothers were and where the family came from in Prussia. Leopold is the right age to be his brother. Any further information?
